Think it's so hard to say, don't think anyone could tell the difference in a blind test. Probably comes down to quality and features. Then again it's only a few bits of wire on a couple of pivots and none of the features are of any use on the hoof.

i've used both and as mentioned there's really not much difference in use although the TRPs might be a little bit more powerful
the Kores are a little bit easier to adjust and they're cheaper, but the TRPs have old-skool 'cross cool
